Bergbach-Waldsänger Myiothlypis signata

Small yellowish warbler of montane forest. Has light pink legs and a pale eyebrow. Compared to the similar Citrine Warbler, has a fainter facial pattern with lighter lores; also tends to be found at lower elevations than that species, although there is significant overlap. Listen for an accelerating series of ringing notes that rise and then fall into a variable chatter.
